CrowdsourcingSince launching in 2010, OpenSignal has built the largest global database on mobile performance.

With hundreds of billions of readings of mobile network signal strength and speed tests, OpenSignal shows the performance where you live. Download the app to automatically contribute data on speed and 2G, 3G and LTE signal, or you can choose to turn off data collection settings.

Totally brilliant found the strongest signal in my house in minutes my WiFi goes there. A direct line to the tower on Google maps I know there a block of town houses messing up my signal brought a kogen signal booster $40au tried other apps don't bother this one I would pay for

Finally a app that lets you use it and not get flooded with useless adds, and does what it says . ( ather

Gives good information but keeps asking for extra personal data permissions without saying why it would be needed. Why do they need access to"microphone",? "contacts"? Or "body sensors"? But works without them, so it's just fishing for data.

The signal just keeps getting stronger and better can you make it get around rural areas too thank you awesome app

Great app. Allthe tools you need to find your best signak where ever you are. Very intuitive and easy to use.

I'm a dedicated user, and leaving it on when driving in fringe areas contributes to a true map of where service is, and more importantly, isn't. The data collected by my phone in previously unmapped areas (which didn't show service for my carrier) were added to the map in a month or so, reflecting better coverage in those areas, and it showed change very precisely! So much better than trusting very questionable carrier coverage maps. Thanks for such a great tool for real-world accuracy! 👍 One problem for me: the arrow which points to my connected tower points exactly opposite, always. Please fix

An excellent application that I found invaluable when identifying and siting a directional 4G aerial for home security. Furthermore, it's refreshingly clean and untarnished by tacky ad's that infuriate a million to make one sale (if that). Full credit to the developers... Thank you!

Great tool for comparing actual signal strength at specific locations. Cell providers coverage maps are just marketing tools, and useless for predicting whether you can actually get a usable signal at a specific location. Open Signal is a big step in the right direction, and will improve over time as more users share signal data.

Still does not show a single tower in the area where I live or downtown. This app falsely advertises that it detects towers and will show you on a map... you open the cell tower map and get nothing, even when leaving your screen on for a ridiculous amount of time

As of most recent update - even when data collection is set to OFF, app is downloading data sets and saving to phone.. App saved approx 2gb of data in less than 24 hrs, causing my low space available alert to pop up. Uninstalled for the time being until this can be resolved.

I love this app it easy too use i vary highly recommend that you down load this app especially like me that i like too know which cell tower that my phone is connected too I've tryed a lot of different cell tower aps but all of them were so hard for me too figer out that im staying with this one

I like the intuitive ui: the tabs, menus, dynamic directional cell-tower locater. OpenSignal even works fine on my old OnePlus1 phone. I wish it also listed which WiFi signal is the strongest/best within the app so I didn't have to open my phone's settings.

📌I just found this app, not to long ago & I must say, it's working VERY💯 WELL & have a few 🔑KEY features you MOST ALL "speed checking/signal testing"apps DO NOT! It DOESN'T have ANY ads popping up, at all!! It actually gives you a lot more in-depth analysis (important measurements)of your device/carrier/network than all the others I've seen. You may also choose to help them build those coverage maps based on data you contribute, which in turn, will help us all get better, more reliable connections & a better network, overall! Just choose the option in the settings menu to send them the results from your speed tests & measurements from your signal readings. You can even customize that option further, by choosing how often: "none, low, normal, med, or high" your device will send those measurements, if at all! (It says the "normal" option will do about 100 readings per day, based on your usage.)✴Finally, the REALLY*IMP*INFO here, is that this app shows you the "REAL", "TRUE" speed you're getting on your network, *WITHOUT OPTIMIZING ANYTHING OR ANY SETTINGS when it's testing! MOST, if not ALL, other apps give you the "MAXIMUM SPEED POSSIBLE" on your network, because they optimize you're settings during testing.😲 When you're using the net, playing games, streaming music/videos, or using any apps you have, nothing is optimized then, so those numbers do you 💯NO🚫GOOD AT ALL!😠 💡Sound misleading or like they're hiding the numbers you actually need to know, which is why your here in the 1st place, right?!🤔 That's what I was thinking... 🌟OpenSignal🏆IS A ✔MUST💯DOWNLOAD!😄 If your sick of walking all over your house to find that one spot where your phone will play games, music, videos, or just make those everyday phone calls, like I was, then you have found prob the ONE "Open" & honest app available...in my opinion, anyway😁...🎁CONGRATS!🎉🥇🎈👑💎💯🏆👍✋👏
